DIRECT the Public Works Director to begin right of way acquisition and to prepare contract plans
and specifications for construction.
DIRECT the Director of Community Development to file a Notice of Determination and a
Certificate of Fee Exemption: De Minimis Impact Finding with the County Clerk.
DIRECT the Public Works Director to arrange for payment of the $25.00 handling fee to the
County Clerk.
II. FINANCIAL IMPACT:
The estimated contract cost of the project is $4,600,000.00 funded by Rodeo/Crockett Mitigation
Fund (50%) and State Funds (50%).
III. REASONS FOR RECOMMENDATION/BACKGROUND:
The project includes the extension of Cummings Skyway from its terminus on the west side of
Interstate 80 to San Pablo Avenue (Old Highway 40).
It is needed to reduce truck traffic on Parker Avenue in Rodeo and San Pablo Avenue in Crockett
and would serve as an entrance to Crockett from Interstate 80.
The project has been determined to be in compliance with the General Plan. A Negative
Declaration of environmental significance pertaining to this project was published June 6, 1997.
The Board has considered the negative declaration together with all comments received during
the public review period and staff's responses to the comments.
This project has been found to be de minimis in its effect on the environment and is exempt from
the $1,250.00 Fish and Game filing fee.
IV. CONSEQUENCES OF NEGATIVE ACTION:
If project approval is delayed, right of way acquisition, design and construction will be delayed and
the State's participation may be jeopardized.

County File #97-24
Pursuant to the State of California Public Resources Code and the "Guidelines for Implementation of the California
Environmental Quality Act of 1970" as amended to date, this is to advise you that the Community Development
Department of Contra Costa County has prepared an initial study on the following project:
Project Name, Description and Location: CUMMINGS SKYWAY EXTENSION PROJECT: The Contra Costa
County Public Works Department proposes to extend Cummings Skyway between the terminus of the existing
Cummings Skyway on the west side of Interstate 80 (1-80) to the east and San Pablo Avenue to the west. The
project involves constructing a 762 m (2,500 ft.), two-lane roadway with a truck-climbing lane, drainage
improvements, and associated ancillary improvements (i.e., left and right-turn lanes, traffic signals, and intersection
modifications) on San Pablo Avenue. The purpose of the project is to provide access, particularly for trucks, to the
industrial areas along San Pablo Avenue from Interstate 80.
Location: The project limits are between the terminus of the existing Cummings Skyway on the west side of
Interstate 80 (1-80) to the east and San Pablo Avenue to the west., in the west Contra Costa County area.
The proposed development will not result in any significant impacts.

REVIEWED BY:jk �Y3JDATE: Hay�qi /99 5L-
RECOMMENDATIONS:
( ) Categorical Exemption (*I) Negative Declaration
( ) Environment Impact Report Required ( ) Conditional Negative Declaration
The project will not have a significant effect on the environment. The recommendation Is based
on the following summary of the Environmental Evaluation:
1. The project will not create unstable earth conditions, changes in geologic substructures or
increase the exposure of people or property to geologic or water related hazards. The project will
be designed and constructed to account for site-specific soils conditions and all grading activities
(e.g. cutt ill)will balance on-site.
2. No significant negative aesthetics will result from the project. Exposed areas will be hydroseeded
with native grasses and wildflowers.
3. The project will not encroach upon habitat of any unique,threatened or endangered species of
animals. No new species of animals will be introduced into the area as a result of the project.
In addition, there will be no removal of fish or wildlife habitat.
4. Some parcels within the project limits are zoned agricultural. Small amounts of some of those
parcels may be acquired for right-of-way purposes. However, the amount to be acquired is
negligible and the parcels will continue to be viable agricultural land upon completion of the
project.
Construction activities will create minor, short-term, temporary impacts. But no significant impacts will
occur since the following best management practices are incorporated into the project and in project
specifications:
5. There will be no long-term significant change in the air quality in the project area. Construction
machinery and vehicles will emit exhaust fumes and possibly objectionable odors during
construction which may temporarily deteriorate air quality. To minimize the impact, contract
specifications shall stipulate the use of properly tuned and muffled equipment. Air quality impacts
will also be reduced by eliminating unnecessary idling of machines when not in use. Dust
palliatives or water may be applied to minimize fugitive dust during construction, covering storage
piles and haul trucks, and suspending excavation activity during periods of high winds, if
warranted, will also reduce impacts.
6. Drainage improvements include installing a small number of culverts where swales exist and
cross the road alignment. This construction shall occur during periods of low or no flow(e.g. April
15 to October 1)to avoid water quality impacts. if water is present, the construction area shall
be de-watered by installing cofferdams and diverting water through a pipe, around the work site,
to be discharged downstream in a non-erosive manner. Furthermore, sediment traps and/or
filters shall be installed on an as-needed basis.
7. Standard construction safety practices shall be followed during construction to ensure no
accidental release of hazardous substances or increase the potential for exposure to these
substances. The project has the potential for interfering with an emergency response,. but
V

emergency response agencies in the area shall be noted prior to the onset of construction.
S. The project may have a temporary impact on the existing transportation system since it may be
necessary to Gose lanes and shift traffic during construction of intersection improvements.This
impact will be minimized by installing sufficient signs warning about the construction.
What changes to the project would mitigate the identified impacts(list mitigation measures for
any significant Impacts and conditional negative declaration). N/A

ENVIRONMENTAL EVALUATION
Cummings Skyway Extension Project
The Contra Costa County Public Works Department proposes to extend Cummings
Skyway between the terminus of the existing Cummings Skyway on the west side of,,
Interstate 80 (1-80) to the east and San Pablo Avenue to the west., in the west Contra
Costa County area. The project involves constructing a 762 m (2,500 ft.), two-lane
roadway with a truck-climbing lane, drainage improvements, and associated ancillary
improvements (i.e., left and right-tum lanes, traffic signals, and intersection modifications).
The purpose of the project is to provide access, particularly for trucks, to the industrial
areas along San Pablo Avenue from Interstate 80.
In the process of preparing the Checklist and conducting the evaluation, the following
references (which are available for review at the Public Works Department, located at 255
Glacier Drive, Martinez, except where otherwise noted) were consulted:

1. Earth
(A - G) The project area is located at the northern end of the Franklin Ridge, within the
East Bay Hills. The area is characterized by moderately steep-sided northwest-southeast
trending ridges and valleys, with elevations ranging from 25 m (82 ft.) to 103 m (338 ft.)
above sea level. According to the County Resource Mapping System, Sehorn clay,
Millsholm loam, and Los Osos clay loam are found in the project area. Runoff from these
soils is medium to rapid and erosion hazard is moderate to high where the soil is bare.
Cropley clay, which has slow runoff and slight erosion hazard, is also found in the project
area.
The County Resource Mapping System did not identify any unique geologic features within
the project area. The Franklin fault, a potentially active earthquake fault, is mapped
approximately 0.6 km (A mi.) to the northeast of the project area. Construction of the
roadway would involve cutting and filling, of approximately 262,000 cubic yards, along its
route, or the use of retaining walls and bridge structures. All grading activities (e.g. cut/fill)
will balance on-site. Activities associated with the project, including grading, will not result
in an increase of exposure to geologic hazards, nor will it result in unstable earth
conditions or changes to a geologic substructure. The project is not expected to result in-
modifications to the channel of any waterway, as a result of changes in deposition or
erosion. ,
As part of the final design process, a subsurface exploratory investigation was conducted
for the proposed project. The information gathered will be used in designing cut and fill
slopes, determining foundation conditions for embankments, culverts, pavements, and
retaining walls, and evaluating corrosion potential for culverts and substructures. All
project facilities will be designed and constructed to account for site-specific soils
conditions and potential geological hazards
The project temporarily increases the exposure of the soil to wind erosion during the
construction phase, but this impact is minor and temporary. Adherence to standard dust
control and erosion control practices during construction including, but not limited to,
general watering of exposed areas, use of chemical stabilizers, covering storage piles and
haul trucks , and suspending excavation activity during periods of high winds will minimize
dust and erosion impacts. :.Disturbed areas will be hydroseeded with native grasses and
flowers upon completion of the project. These measures shall be incorporated into the
construction contract.
2. Air
(A- B) Short-term emissions and objectionable odors are generated during construction
activities, but they are minor and temporary (See Traffic, Air, and Noise study prepared by
EIP Associates - May 1997). Contract specifications shall stipulate the use of properly
tuned and muffled equipment and the elimination of unnecessary idling of machines when.
not in use. These measures could reduce construction period emissions by up to 50
percent. Implementation of dust control practices noted in #1 - Earth (A - G), also
minimizes air quality impacts. Since there are no sensitive receptors along the alignment
of the proposed Cummings Skyway Extension, the project will not result in exposure of
people to significant air quality impacts.
(C) Constructing the road will not cause an alteration of climate, air movement, moisture,
or temperature.
ENVIRONMENTAL EVALUATION

3. Water
(A- I) According to the Contra Costa Resource Mapping System, the project area is not
in a flood hazard area. Extending the roadway will not increase the exposure of people;
or property to flooding. Drainage improvements include installing culverts where there are
existing swales. Construction of the culverts shall occur during periods of low or no flow
(e.g., April to October)to avoid water quality impacts. If water is present, the construction
area shall be dewatered by installing water diversion structures and diverting water
through a pipe, around the work site, to be discharged downstream in a non-erosive
manner. During construction, sediment traps and/or filters shall be installed on an as
needed basis, minimizing water quality impacts.
Drainage improvements will not impair the flow of water in marine or fresh waters, nor will
they alter the course or flow of flood waters. Extending Cummings Skyway would increase
the amount of impermeable surface by approximately 1.6 hectares (4 acres). This would
result in a slight increase in storm water runoff that would be directed to local drainage.
Considering the urban area, the existing highway and local street network, and other
paved surfaces such as structures and parking lots in the region, the increase in runoff
from the Cummings Skyway Extension would be negligible. An intermittent drainage
channel extends through the northwest end of the Cummings Skyway Extension project
area, parallel to and southeast of San Pablo Avenue. A seep provides year-round surface
water to a narrow drainage course within the corridor of the Cummings Skyway Extension
Project. Culverting portions of an intermittent drainage channel and a year-round drainage
channel will not significantly affect the quantity or quality of surface waters. In addition,
the project will not affect the quantity or quality of ground water, irrigation water or public
water supply. Standard construction safety practices (see #2 - Air {A - B) and #13 -
Transportation/Circulation {A - D)) shall be followed in order to reduce the possibility of a
spill of gasoline, oil, or other pollutants which could have a significant impact on water
quality.
4. Plant Life
(A- D) Plant life in the project area includes annual grassland and central coast riparian
scrub. Arroyo willow and red willow form a dense low-lying canopy with a subshrub layer
of western poison oak and Himalayan blackberry in the drainage course with year-round
surface water. Saturated zones support narrow-leaved cattail, common rush, tule, wild
celery, iris leaved rush, marsh baccharis, water cress, toad rush, low clubrush, and false
nutsedge. Upstream portions of the drainage have been trampled by cattle, water quality
is poor, and areas are barren of vegetation. In the intermittent drainage channel; parallel
to and southeast of San Pablo Avenue, scattered red willows form a sparse canopy cover,

with an understory of Mediterranean barley, meadow barley, pale spikerush, tuberous
rush, and bristly ox-tongue. Vegetative cover is sparse as a result of grazing and
trampling by cattle.
According to the EIS for the I-80/Carquinez Bridge Project, repeated seasonal surveys did
not reveal the presence of any listed, proposed, species of concern, or candidate plant
species in the project area. Thus, the proposed project is not expected to result in the
reduction of the numbers of any unique, rare or endangered species. The project will not
result in the significant reduction of any agricultural crop. Although a minimal amount of
right-of-way may be acquired from some parcels zoned for agricultural purposes, the
parcels will continue to be viable agricultural land upon completion of the project. The
project will result in a loss of grassland. However, given the poor condition of the plant life
(i.e., sparse grassland and trampled by cattle), the loss will not be a significant impact. In
addition, areas disturbed by grading will be hydroseeded with native grasses and flowers
upon completion of the project.
5. Animal Life
(A - D) The project will not result in a significant reduction of any unique, threatened or
endangered species of animals according to the County Resource Mapping System, field
reviews, review of RAREFIND, and the EIS for the I-80/Carquinez Bridge Project. No new
species of animals will be introduced into the area as a result of the project. Areas
exposed by grading will be hydroseeded, which will provide habitat for animal life. In
addition, the project will not result in the deterioration to existing fish or wildlife habitat.
6. Noise
(A - B) The dominant source of noise in the project area is from traffic on 1-80 and San
Pablo Avenue. The County Resource Mapping System for the project area indicates a
noise level for 1-80 of 75 dBA and a noise level of 70 dBA for San Pablo Avenue. This was
confirmed by measurements made by EIP Associates along San Pablo and Pomona
Avenues, which showed existing noise levels of about 61-70 dBA (See Traffic, Air and
Noise study prepared by EIP Associates. The projected noise level for the extended
roadway will not exceed the year 2005 projection. Since there are no sensitive noise
receptors along the alignment of the proposed Cummings Skyway Extension, the project
will not result in exposure of people to severe noise levels.
Extending Cummings Skyway will temporiarly increase the noise level of the project area
during construction. In general, construction activities produce noise levels of 86 dBA at
50 feet which is well below the threshold of pain of 120-140 dBA. Best management

practices noted in #2 - Air (A - B) reduce construction noise levels and shall be
incorporated as part of the construction contract.
7. Light and Glare
Extending Cummings Skyway and associated ancillary improvements (i.e., traffic signals,
etc.) may produce a minor amount of new light or glare. However, since there are very
few sensitive receptors in 'the semi-rural area, the increase of new light or glare is
insignificant.
8. Land Use
The existing land uses within the project area consist of agricultural activities (cattle
grazing), rural-residential, East Bay Municipal Utilities District water reservoir to the
southwest, and the Unocal Refinery also to the south. The proposed project is consistent
with the following County General Plan policies:
• 3-148 - Extend Cummings Skyway west of 1-80 to San Pablo Avenue to provide
direct freeway access for industrial traffic, to minimize industrial traffic through
Crockett and Rodeo, and direct east-bound regional traffic from the San Pablo
reliever route back onto 1-80 prior to entering Crockett.
• 3-156 - A large vacant parcel owned by the County located adjacent to 1-80
northeast of the Wickland Oil Company tank farm is designated Public and Semi-
Public. This property is to be reserved for construction of a planned industrial
arterial road between 1-80 and San Pablo Avenue.
Open industrial and agricultural (grazing) land uses would be changed to accommodate
extension of transportation uses. The land use changes would result in approximately 0.4
hectare (one acre) of prime and unique farmland being converted to non-agricultural use.
This represents approximately 0.0014% of the available farmland in Contra Costa County.
In compliance with the Farmland Conversion Rating Form (AD-1006) a map of the
proposed project was submitted to the Natural Resources Conservation Service. The total
site assessment criteria score for the project is 97 points. Based on regulation (7CFR
658.4) of the Natural Resources Conservation Service, which provides that "sites receiving
a total score of less than 160 points be given a minimal level of consideration for protection
and no additional site be evaluated".
Right-of-way for the road construction, including construction and slope easements, is
needed for the project. The majority of the right-of-way will be dedicated to the County as
a condition of approval for the Pointe Crockett subdivision. The proposed project will not
result in a substantial alteration of the present or planned land use of an area.

9. Natural Resources
Implementation of the project will involve the use of paving materials (i.e., asphalt) which
will not significantly impact this resource. The use of oil and gasoline to operate the
machinery for construction purposes is negligible and of a short-term, temporary nature.
The temporary expenditure of resources will end with the completion of the project. Best
management practices, e.g., using properly tuned equipment and eliminating unnecessary
idling of machines as previously noted in #2 -Air (A - B) also minimizes the consumption
of natural resources.
10. Risks of Upset
(A) Fuel trucks accessing the Unocal and Wickland Oil Refineries will be directed to use
the Cummings Skyway Extension from 1-80 to San Pablo Avenue. Thus the transport of
hazardous materials along existing truck routes, which bisect the communities of Rodeo
and Crockett, would be reduced.
The project has the potential to release hazardous substances, such as accidental
petroleum spills, during construction. Per specifications, standard construction safety
practices (see #2 - Air (A - B) and #13 - Transportation/Circulation (A - D)) shall be
followed during construction to ensure no accidental release of hazardous substances or
increase the potential for exposure to these substances. The County Resource Mapping
System for the project area identified overhead transmission lines at San Pablo Avenue.
Measures, such as coordinating with the appropriate utility agencies prior to construction,
ensures that the pipeline will not be disturbed during construction activities.
(B) The project has the potential of interfering with an emergency response, but
emergency response agencies in the area shall be notified prior to the onset of
construction.
11. & 12. Population & Housing
The project will not result in a change in the location, distribution, density, or growth rate
of human population in the area. The project will not affect existing housing, or create a
demand for additional houses (see #8 - Land Use).
ENVIRONMENTAL EVALUATION
Cummings Skyway Extension Project

13. Transportation/Circulation .
(A - D) According to the County General Plan, the Cummings Skyway Extension is
designated as a proposed expressway. Extending Cummings Skyway is consistent with
the following policies in the County General Plan:
• 3-147 - Discourage industrial traffic that could impact the safety and efficiency of
Crockett's no-industrial and emergency vehicle traffic.
• 3-148 - Extend Cummings Skyway west of 1-80 to San Pablo Avenue to provide
direct freeway access for industrial traffic, to minimize industrial traffic through
Crockett and Rodeo, and direct east-bound regional traffic from the San Pablo
reliever route back onto 1-80 prior to entering Crockett.
• 3-156 - A large vacant parcel owned by the County located adjacent to 1-80
northeast of the Wickland Oil Company tank farm us designated Public and Semi- .
Public. This property is to be reserved for construction of a planned industrial
arterial road between 1-80 and San Pablo Avenue.
• 5- 8 - Existing circulation facilities shall be improved and maintained by eliminating
structural and geometric design deficiencies.
• 5 - 10 - The use of freeways for community circulation shall be minimized by
providing sufficient arterials and expressways.
As mentioned in #10-Risk of Upset, fuel trucks accessing the Unocal and Wickland Oil
Refineries will be directed to use the Cummings Skyway Extension from 1-80 to San Pablo
Avenue. Thus the transport of hazardous materials along existing truck routes, which
bisect the communities of Rodeo and Crockett, would be reduced.
Extending Cummings Skyway will generate additional traffic during construction when
vehicles associated with those activities utilize the local street system. Constructing the
new roadway will not create a demand for new parking.
It may be necessary to close lanes and shift traffic during construction, so the project may
have a temporary impact on the existing transportation system. The potential for traffic
hazards to motor vehicles increases, however, this temporary impact ends upon
completion of the project. These temporary impacts will be minimized by installing
sufficient signs warning about the construction. The staging area for construction
equipment will be within the existing right-of-way, and since there are few residences in
this area the impacts are minimal.
ENVIRONMENTAL EVALUATION
Cummings Skyway Extension Project
Page 8
(E & F) No water, rail, or air transportation and facilities are located near the project area,
thus the project will not alter waterborne, rail, or air traffic. Once complete, the project will
result in better truck access to the refineries and reduce congestion in the communities of
Crockett and Rodeo.
14. Public Services
(A - D, F) Constructing the new roadway will not increase the need for fire or police
protection, schools, parks or other governmental services (see # 8, 11 & 12 - Land Use,
Population & Housing).
(E) The Cummings Skyway Extension will be maintained by the County. San Pablo
Avenue is currently maintained by the County. Periodic maintenance of road
improvements will continue to be performed by the County.
15. Enerav
(A- B) Minor amounts of non-renewable fuel resources are consumed during construction,
but this is a short-term, temporary impact. This impact is reduced to an insignificant level
by eliminating unnecessary idling of machines when not in use and by using properly
tuned equipment as mentioned in #2 -Air (A - B) and #9 - Natural Resources.
16. Utilities
Measures discussed under #10 - Risk of Upset ensures there is no disturbance to the
utilities in the project area.
17. Human Health
The project has the potential to release hazardous substances during construction.
However, the project is in a rural-residential and agricultural area and is not in the
immediate proximity of sensitive receptors which minimizes the likelihood of impacts.
Potential health hazards due to accidental petroleum spills shall be minimized by following
best management practices noted in #10 - Risk of Upset (A). Air quality impacts, which
could affect human health, can be minimized by the measures noted in # 2 -Air (A - B).
Extending the road and associated drainage improvements will not create any known

Cummings Skyway Extension Project
Page 9
health hazard or result in the exposure of people to potential health hazards. As
mentioned in #10 - Risk of Upset and #13 - Transportation, fuel trucks accessing the
Unocal and Wickland Oil Refineries will be directed to use the Cummings Skyway
Extension from 1-80 to San Pablo Avenue. Thus the transport of hazardous materials
along existing truck routes, which bisect the communities of Rodeo and Crockett, would
be reduced.
18. Aesthetics
Grading of the hillside near the northwest project limits will not create in an aesthetically
offensive site since exposed areas will be hydroseeded with native grasses and
wildflowers upon completion of the project. The sight of construction equipment may be
visually unattractive, but this is a minor and short term impact, ending upon completion of
the project.
19. Recreation
The project will not result in an impact upon the quality or quantity of the San Pablo Bay
Regional Trail or any other recreational opportunities.
20. Cultural Resources
(A- D) The County General Plan has designated the project area as a largely urbanized
area excluded from the archeological survey. A cultural resources investigation was
conducted in accordance with Section 106 of the National Historic Preservation Act for the
I-80/Carquinez Bridge Project. No archaeological sites were identified in the entire project
area. Although, sixty-four properties constructed prior to 1946 were identified and
evaluated within the entire 1-80/Carquinez Bridge Project area, none of these properties
are within the project limits of the Cummings Skyway Extension project. The contract
specifications shall include measures related to discovery of cultural resources.
21. Mandatory Findings of Significance
(A - C) Due to construction activities, air quality may be temporarily degraded at the
project site. However, no permanent long-term impacts will result (see#2 -Air, and Traffic,
Air, and Noise Study prepared by EIP Associates - May 1997). The proposed project will
ENVIRONMENTAL EVALUATION
Cummings Skyway Extension Project
Page 10
not substantially reduce the habitat of a fish or wildlife species, nor will it cause fish and
wildlife population to drop below self sustaining levels. In addition, the project will not
threaten to eliminate a plant or animal community, significantly reduce the number or
restrict the range of a rare or endangered plant or animal (see #4 - Plant Life and #5 -
Animal Life). The project does not have the potential of eliminating examples
of the major periods of California history or prehistory(see#20- Cultural Resources). The
minor individual impacts identified are not cumulatively considerable (see #2 - Air, #4 -
Plant Life, #5 - Animal Life, and #13 -Transportation/Circulation). In addition, there will
be no adverse environmental effects on human beings (see #17 - Human Health).

SUMMARY OF PUBLIC MEETING ON THE
CUMMINGS SKYWAY EXTENSION PROJECT AND THE
SAN PABLO AVENUE GENERAL PLAN AMENDMENT AND RESTRIPING PROJECT
HELD IN RODEO ON MONDAY,JUNE 23, 1997
The Contra Costa County Public Works Department held a public meeting in Rodeo on the evening of June
23, 1997 to present information on the proposed Cummings Skyway Extension Project and the San Pablo
Avenue General Plan Amendment and Restriping Project. Julie Bueren and Jerry Fahy from the Public Works
Department as well as Bill Dietrich and Barbara Sahm from E.I.P. Associates and Mark Bowman from
Dowling Associates who prepared the air quality, noise and traffic studies were at the meeting to present
information and answer questions.Julie Bueren started by giving background information on the two projects
that included a general project description and information on the funding.
CUMWNGS SKYWAY EXTENSION .
The project extends Cummings Skyway from I-80 to San Pablo Avenue. It has been on the County
General Plan since 1978.With the Unocal(now Tosco) clean fuels project, Unocal was conditioned
to contribute $4.5 million for transportation improvements in the Rodeo/Crockett area. At special
meetings of the Board of Supervisors Transportation Committee held in Rodeo and Crockett, the
communities prioritized projects for funding from the$4.5 million. Cummings Skyway Extension was
determined to be the first priority project for the funds. As part of the mitigation for the Carquinez
Bridge Replacement Project, Caltrans has agreed to fund half of Cummings Skyway Project up to
$3.25 million. Therefore, the project is fully funded and there should be funds left over from the
Unocal money for other projects in the area.
SAN PABLO AVENUE GENERAL PLAN AMENDMENT AND RESTROING PROJECT
This project involves restriping San Pablo Avenue from First Street in Rodeo to I-80 in Crockett to
provide one 3.6 meter(12 foot)traffic lane in each direction, one 1.83 meter(6 foot) bicycle lane in
each direction and one 3.6 meter(12 foot) auxiliary lane to be used as either a truck climbing lane,
two way left turn lane, or left turn channelization depending on the segment of road.
The conditions of approval for Unocal's clean fuels project require Unocal to dedicate an easement
on their service road for trail use and to contribute $100,000 for construction of the path. There are
no provisions to continue the two way facility beyond Unocal's frontage. In working with Unocal to
develop plans for the trail, it was determined that a two way facility along Unocal's service road
would terminate on San Pablo Avenue at locations where it would be difficult to provide a safe
crossing,for the trail users. Therefore, we looked for other opportunities to provide for a continuous
bicycle and pedestrian facility along San Pablo Avenue. The restriping project provides for continuous
bicycle lanes from Rodeo to Crockett and provides a connection for the Bay Trail. The project also
enhances the safety of San Pablo Avenue without reducing the level of service by providing left turn
channelization, shoulders and truck climbing/passing lanes on the steep grades.
This project conforms to other related projects on San Pablo Avenue. Approval of the Pointe
Crockett project included reconfiguring San Pablo Avenue to a two lane facility with--left turn ' a
channelization to provide access into the proposed subdivision. In addition, the County and the
community of Rodeo are working on the Rodeo Waterfront/Downtown Specific Plan. The draft plan
calls for making Parker Avenue from its connection with San Pablo Avenue a two lane roadway with
a median and extensive landscaping. The plan has been approved by the County Planning Commission'
and will go to the Board of Supervisors for approval. Taken together, these two actions will modify
San Pablo Avenue at both its north and south ends to a two lane facility with left turn channelization.
ISSUES/CONCERNS RAISED BY THE PUBLIC
This was not a recorded public hearing. The following is an attempt to summarize the issues and questions
raised at the meeting. The main areas of concern were traffic safety and operations, traffic volumes, air quality
and noise.
TRAFFIC SAFETY AND OPERATIONS
Issue/Concern:
There was a lot of concern about the restriping project's impact on traffic safety. Many expressed
concern that by reducing the number of traffic lanes that the safety of the road would be reduced.
There was concern that with only one through lane in each direction, there would be more unsafe
passing. It was stated that there is an existing problem with a lot of teenage drivers driving at unsafe
speeds and that this project would make it worse.
Staff Response:
Public Works staff and the traffic consultant for the project stated that they believe the project to be
a safety improvement. The provision for left turn channelization at intersections and for truck
climbing/passing lanes on the hills and the addition of shoulders are all safety enhancements. We are
also proposing to use raised buttons for the centerline stripe to better.inform drivers of when they
cross the centerline and are considering other safety enhancements such as lighting.
Public Works has looked at the accident data for San Pablo Avenue from 1990 through 1996. In
those 7 years there were 38 reported accidents on San Pablo Avenue between Parker Avenue and
Pomona which translates into an accident rate of 1.25. The accident rate is based on the number of
total accidents,the length of road and the traffic volume. The rate for San Pablo Avenue is below the
state average of 1.9 for a 4 lane undivided road in rolling/mountainous terrain, rural and 4.2 for an
undivided 4 lane road with a speed limit less than 55 mph, suburban.
Of the 38 accidents, 22 were property damage only, 14 resulted in injuries and 2 resulted in fatalities.
19 of the accidents were the result of unsafe speed, 8 were from improper turns, 3 from failure to
yield right of way, 2 from unsafe lane changes, 4 from improper driving, 1 from mechanical failure
of a vehicle and 1 from driver illness. 6 of the accidents involved a driver under the influence of
alcohol or drugs. 19 of the accidents involved a single car, 18 involved two vehicles and 1 accident
involved 3 vehicles.
Issue/Concern:
Will the speed limit be lowered?
Staff Response:
Speed limits are set based on the design parameter of the road and the eighty fifth percentile speed =
(85% of the drivers drive at or below the eighty fifth percentile speed). We are required to`use speed
surveys to establish the speed limit on a road for radar enforcement. Three speed surveys were
conducted on San Pablo Avenue in April 1993. At Railroad Avenue the eighty fifth percentile speed
2
ranged between 38 and 41 miles per hour(mph). Approximately 0.6 miles west of Old County Road
the eighty fifth percentile speed was 50 mph. Approximately 0.42 miles west of Merchant Street the
eighty fifth percentile speed ranged from 49 to 53 mph.
We anticipate that the eighty fifth percentile speed may drop in some locations on San Pablo Avenue
due to the restriping project. We would conduct new speed surveys after the project is complete to
establish the appropriate speed
Issue/Concern:
The Cummings Skyway Extension Project includes a traffic signal at San Pablo Avenue. There was
concern that the signal would be difficult to see by drivers coming down San Pablo Avenue from
Crockett and that there would not be time to stop. There was also concern about stopping trucks
heading from Rodeo up the hill before they could make the right turn onto Cummings and a free right
was suggested.
Staff Response:
The signal would be designed to consider sight distance and appropriate advanced warning would be
included in the project. Staff will look into the possibility of accommodating a free right for eastbound
San Pablo traffic onto Cummings Skyway.
Issue/Concern
Will there be a left turn provided from San Pablo Avenue to Old County Road.
Staff Response
Yes.
TRAFFIC VOLUMES/CONGESTION
Issue/Concem
There was concern that by reducing the number of through lanes, traffic congestion would be worse.
The traffic data was questioned. Was school traffic considered? Were County staff and the traffic
consultant aware of a rise in school bus fees which will encourage more students to commute by car?
A resident of Tormey stated that it is currently very difficult to make a left onto San Pablo Avenue
from Old County Road during shift changes for the refinery because of the heavy traffic on San Pablo
Avenue and that reducing the lanes would make it more difficult.
Staff Response:
San Pablo Avenue currently operates at Level of Service A which means it operates well with very
little delay. The traffic study included a 24 hour count of existing traffic in each direction on San
Pablo Avenue just east of Old County Road. The count was taken midweek in December 1996 when
school was in session. The total volume was 3,900 vehicles. The morning peak occurred around 6
a.m. with about 350 cars per hour in the westbound direction and 125 in the eastbound direction. The
afternoon peak occurred at about 3:00 p.m. with approximately 400 cars per hour eastbound and 125
westbound.
The County also has a record of.traffic counts conducted in June 1994 east of Wanda Street. These
counts were also taken midweek while school was in session. The total volume for a 24 hour period
was 5,546 (2,687 eastbound and 2,859 westbound). The morning peak hour was 6:30 to 7:30
eastbound with 131 vehicles and 6:15 to 7:15 westbound with 410 vehicles. The afternoon peak hour
was 3:30 to 4:30 eastbound with 404 cars and 2:15 to 3:15 westbound with.185 cars.
Neither County staff nor the traffic consultant was aware of a potential change in the number of
students commuting by car because of increases in school bus fees, so this information was not
considered. However, it would not be likely that the level of service of San Pablo Avenue would be
impacted if more students were to drive to school. Even with the restriping project, San Pablo
Avenue will have excess capacity. The level of service of a road is impacted by intersections with
heavy side street volumes.
Issue/Concem:
Questions were raised about future traffic and congestion.
Staff Response:
The traffic study used the West County Travel Demand Forecasting Model as the basis for analyzing
the effects of the proposed project on nine intersections. The existing roadway network was modified
to reflect project conditions;Cummings Skyway was added as a basic two lane facility and San Pablo
Avenue was modified to the proposed two lane facility. Project impacts were not found to be
significant. Three intersections analyzed were shown to be negatively impacted by the project and five
were shown to be positively impacted. Two of the negatively impacted intersections are at the I-
80/Cummings Skyway Interchange which is due to the additional movements required by the
extension of Cummings Skyway. The third negatively impacted intersection is at San Pablo Avenue
and John Muir Parkway. This is primarily due to the heavy right turn movement from northbound San
Pablo Avenue which exists with or without the Cummings Skyway Extension or the San Pablo
Avenue restriping project.
The West County Model forecasts 6,900 vehicles per day on San Pablo Avenue for the year 2000 and
5,900 vehicles per day for the year 2010. These volumes can easily be accommodated by the
proposed project. One traffic lane can accommodate up to 1000 vehicles per hour depending on the
number of intersections and the volume of side street traffic.
Issue/Concern:
Will reducing the lanes on San Pablo Avenue impact Rodeo's chance to get the train station?
Staff Response:
If the train station were to be located in Rodeo, it would require a specific traffic study to determine
the impacts and whether any road improvements would be required. This project does not preclude
additional widening to provide access to the train station.
Issue/Concern:
It was stated that it is already difficult and unsafe for people on Old County Road to get onto San
Pablo Avenue because of the way the intersection is configured.
Staff Response:
County staff will look at the intersection of Old County Road to see if any safety improvements are
needed.

AIR OUAL'rrY
Issue/Concern:
The concern is that the supporting berm for the Cummings Skyway Extension would form an air dam
and trap polluted air or increase fallout in Tormey from the nearby refinery and increase the
associated health risks.
Staff Response
The air quality analysis considered the potential impact of the roadway embankment creating an air
dam. It was found that the project would cause no significant increase in depositions of particulates
or concentrations of toxic gasses or odors in Tormey. The predominate wind direction is west-
southwest and it carries emissions and particulates from the Tosco Refinery toward and over Tormey.
The wind then comes up against the small hill directly east of and adjacent to Tormey and a larger
hill southeast of Tormey and San Pablo Avenue. The central portion of the proposed Cummings
Skyway would lie behind this larger hill. The portion of the Cummings Skyway Extension that
connects to San Pablo Avenue will be built on an embankment forming an additional small hill beyond
Tormey. When an air mass approaches an obstacle, such as a hill or berm, the air flow accelerates on
the leading edge. The air becomes compressed as it flows over the hill, and wind velocity increases.
Particulates suspended in the air do not tend to fall out on the windward side; instead their speed
increases with the increase in air speed. As the air mass goes over the hill, decompression occurs,
wind velocity drops and there is turbulence on the leeward side of the hill. When the air slows down,
particulates in the air slow down and increased deposition may occur on the leeward side. The same
aerodynamics apply to gasses. Toxic air pollutant would be carried with the wind over the
embankment. Therefore, the embankment for Cummings Skyway Extension would not result in any
significant increase in particulate fallout or concentrations of toxic gasses in Tormey.
NOISE
Issue/Concern:
What are the noise impacts of the project for Tormey with the increased truck traffic going to
Cummings Skyway?
Staff Response:
The proposed Cummings skyway Extension would provide a more direct route to the area of San
Pablo Avenue near oil and gas facilities from I-80 and would somewhat reduce traffic and traffic
related noise levels on San Pablo Avenue in Rodeo and on Pomona Avenue in Crockett. Noise levels
along the new roadway alignment would increase, but would not cause significant noise impacts to
any sensitive receptors along Pomona or San Pablo Avenues. There are no sensitive receptors along
the alignment of the proposed Cummings Skyway Extension.
Two residential sites were measured on Old County Road in Tormey. The first site is immediately
adjacent to San Pablo Avenue and measurements were taken at a location about 1.5 meters (5 feet)
from the edge of the road. Traffic was the only major noise source at this location. The second site
is on Old County Road near the end of the paved road. The main source of noise, traffic on=San
Pablo Avenue, was attenuated by distance and topography and was not significant. Therefore, this
site was not used in further analysis.
Traffic noise modeling was conducted to analyze the existing conditions with and without the
proposed project as well as year 2010 conditions with and without the proposed project. The analysis
compares the existing noise levels to after project noise levels to determine whether the project causes
a significant increase in noise levels. The noise modeling results show that the proposed project would
decrease noise levels along on San Pablo Avenue east of the proposed Cummings Skyway Extension,
increase noise somewhat at the receptor site in Tormey and have little effect at the sites modeled in
the Rodeo and Bayo Vista areas. With construction of the Cummings Skyway Extension, all sites
modeled except the residential site in Tormey would show either the same or slightly reduced 24 hour
average noise levels. The site in Tormey would increase by about 0.5 dBA over the existing levels.
Since a change in noise levels of less than 3dB is generally considered imperceptible, these predicted
changes would probably not be noticed by most residents and are not considered significant.
Issue/Concem:
The reliability of the noise modeling was questioned. What if after the project is completed the noise
is worse than predicted?
Staff Response:
The county is willing to measure the noise levels after the project is completed. If it is found that there
is a significant change from before project conditions, the county will work with the community to
mitigate the problem.
ALIGNMENT OF CU WMNGS SKYWAY EXTENSION
Issue/Concern
It was brought up that residents of Tormey had preferred the alignment that would connect to San
Pablo Avenue west of Tormey.
Staff Response
Initially we looked at two alignments for the Cummings Skyway Project: 1) runs from I-80 on the
east side of the East Bay Municipal Utility District's(EBMUD)water tank and connects to San Pablo
Avenue east of Tormey; 2) runs west of the water tank and connects to San Pablo Avenue west of
Tormey. The east alignment is preferred as a facility for trucks as it is less steep than the west
alignment. Also,there are difficulties with right of way for the west alignment, while the right of way
for the east alignment is relatively clear.
At early meetings on the project, a resident from Tormey expressed preference for the west alignment
or that the east alignment be placed on a structure to prevent additional air quality impacts from an
earth fill trapping polluted air over Tormey. A study of this potential impact was included in the air
quality analysis for the project and it was found that the earth fill would not have an impact on the
air quality for the community of Tormey. Therefore, we are proceeding with design for the east
alignment of the Cummings Skyway Extension.
CONSTRUCTION IMPACTS
Issue/Concern-
Will the contractor use Old County Road as access for the construction of the Currimirigs Skyway.,
Extension?
6
Staff Response:
No. We will include a restriction on the use of Old County Road in the specifications for the project.
We anticipate the contractor will access off of I-80.
SCHEDULE
Issue/Concern:
What happens next?
Staff Response
An Initial Study of Environmental Impacts for the Cummings Skyway Extension Project has been
prepared and is out for public review. The public comment period ends July 7, 1997. If there is
additional public comment not reflected in this meeting summary, please send your comments in
writing or call the Public Works Department prior to July 7, 1997. The address, telephone and FAX
numbers are shown below.
After the public comment period closes, the project will then go to the Board of Supervisors
Transportation Committee for a recommendation to the full Board of Supervisors on approval of the
Negative Declaration. All of the environmental studies and public comment received, as well as-these
notes from the public meeting will be presented to both the Transportation Committee and the Board
of Supervisors. Once the environmental process is complete, we will begin right of way acquisition
and complete the final design. We are currently scheduled to advertise for bids in December 1997 and
begin construction in Spring 1998.
The San Pablo Avenue General Plan Amendment and Restriping project was included in the
environmental studies but is not part of the Cummings Skyway Extension Initial Study and Negative
Declaration. The General Plan Amendment will go to the Planning Commission and then the Board
of Supervisors for approval. These meetings have not been scheduled. County staff plans to have
additional meetings with the affected communities to work towards making San Pablo Avenue a safer
road for both vehicular and bicycle traffic while not reducing the level of service of the road.

SUBJECT: Cummings Skyway.Extension Project: Notice of Public Review and Intent
To Adopt a Proposed Negative Declaration, County File#97-24
Dear Ms. Chamberlain:
Thank you for the opportunity to review the environmental documentation for the subject
project. The District has the following comments regarding this project.
IMPACT TO DISTRICT FACILITIES
The proposed road will.traverse the District's Selby Reservoir property. Selby Reservoir
is a 9.7 million-gallon reservoir that serves portions of western Contra Costa County.
This reservoir is an essential element of the District's water distribution system.
Mitigation measures to prevent any impacts to this facility are necessary in the design and
construction of this project.
The project sponsor should work closely with EBMUD's Real Estate Services and Design
Division. EBMUD's Real Estate Services can be reached at (510) 287-1244 regarding
right-of-way issues. For issues concerning construction on the Selby Reservoir property,
telephone EBMUD's Design Division at (510) 287-1019.
Further analysis may prove that the road project is incompatible with the operation and
maintenance of the reservoir. In this case; the project sponsor will have to n rsue a,,
alternative alignment for the roadway.
WATER SERVICE
To help mitigate the impact of the additional water demands on EBMUD's finite water
supply, EBMUD recommends that water conservation measures be incorporated into the
design and construction of the proposed project. EBMUD also encourages the use of
equipment, devices, and methodology for irrigation use that furthers water conservation
and provides for long-term efficient water use. EBMUD encourages the use of drought-
resistant plants, use of inert materials, and minimal use of turf areas. The project sponsor
should contact EBMUD's Manager of Water Conservation at(510) 287-0591 for more
information.

A review of the environmental document for the Cummings Skyway ExtenFion Project has been
completed. The project plan does not indicate if signals will be installed at'the I. 80 offramps at
Cummings Skyway or if only stop signs will be used. Area believes the increased truck traffic on
this ramp would most probably require signals. Additionally,there will probably be a need fbr

RE: Negative Declaration, Cummings Skyway Extension Project (File# 97-24) John sutter
Par o Brien
General Manager
Dear Ms. Chamberlain:
Thank you for referring the Negative Declaration for the proposed Cummings Skyway Project to
the District for review. We would like to offer the following comments:
Recreation.
Sections 14f, 19, and p.9 indicate that the project will not have any impact on recreational
resources or on the Bay Trail. In fact, the Cummings Skyway Extension is viewed by the District
as an important connector trail between the Bay Trail, which is planned to run as a bike lane along
San Pablo Avenue at the western terminus of the Cummings Skyway Extension project, and the
District's recently acquired C&H property to the east of I-80, which will become part of the
Carquinez Regional Shoreline. A Contra Costa County Transportation staff report on the status
of the Carquinez Bridge Seismic Retrofit Project, dated March 3, 1997 (page 4) states: "The
Cummings Skyway Extension Project will include shoulder to accommodate bicycles and
pedestrians from San Pablo Avenue to I-80." Class II bicycle lanes on the Extension should join
with bike lanes on the existing Cummings Skyway. The Negative Declar•atiorz shozild allude to
V' proposed bike lanes at the referenced sections.
Traffic hazards to motor vehicles, bicyclists and pedestrians (13f).
The above-referenced bicycle lanes should also be considered as a safety improvement, extending
the lanes on the existing Cummings Skyway. Because of insufficient width of the existing I-80
overcrossing, these lanes do not extend across the overcrossing, thus creating a pinch-point and
bicycle safety hazard at that point. As stated in the Negative Declaration, "The purpose of the
project is to provide access, particularly for tructks, to the industrial areas along San Pablo
Avenue from Interstate 80." (p. 1) Bicycle and pedestrian safety is therefore of particidar
concern, and should be noted in the document. The District recognizes that the I-80
overcrossing is not part of the County's project, and supports the County in encouraging Caltrans
to widen the I-80 overcrossing to provide a safer bicycle and pedestrian connection between the
Carquinez Bridge and the Bay Trail segment on San Pablo Avenue.
Land Use (8).
Comment on section 8 states: "The majority of the right-of-way will be dedicated to the County
as a condition of approval of the Pointe Crockett subdivision." The District believes that a
U 2950 Peralla Oaks Court P.O. Box 5381 Oakland, CA 94605-0381 Tel:(510)635-0135 TDD:(510)633-0460 Fax:(510)569-4319
condition of approval of the Pointe Crockett subdivision specifically provides for reservation of
right-of-way parallel to the Cummings Skyway for a Class I multi-use (bicycle, pedestrian,
equestrian) trail to be built in the future, which would connect the District's Caruinez Regional
Shoreline(C&H property) with the Bay Trail in the Rodeo area. Right-of-way reserved for the
Cummings Skyiiay Extension should recognize this condition, and should avoid impacting right-
✓ of-1vay reserved for this f►cure trail according.to the County's condition on the Pt. Crockett
subdivision.
The Park District appreciates the opportunity to provide comments on the Cummings Skyway
Extension Project. Please refer any questions to Steve Fiala, Trails Specialist, at 635-0138 ext.
2602 or to myself at 63 5-013 8 ext. 2623.

Dear Ms. Bueren:
I am a resident of Tormey and have been all of my life. I represent the community
under the title of Tormey Citizens. Although we may be small in number, we all have
many relatives and friends in the neighboring communities of Crockett and Rodeo who
support our view on these issues.
We have reviewed the summary of the public meeting held in Rodeo, CA on Monday,
June 23, 1997. The summary is a canned report of your presentation given to us at
that meeting. Unfortunately, your presentation was without any feeling for the Tormey
community.
1 . On page two, you state that .out of thirty-eight accidents there were only two (2)
fatalities. You were told at the Monday meeting that there were in fact four (4)
deaths. Three of the accident victims were students and were killed at the
approximate point where you propose Cummings Skyway should enter San Pablo
Avenue. The fourth victim was killed at the Wickland Oil intersection. This
accident involved a truck and an auto.
2. Although it appeared that you had all of the facts, you did not tell us how many
more truck trips, on a daily basis, would be made by the Union Oil coke trucks, acid
trucks and sulfur trucks with only one-half of the present lane capacity.
3. You stated that there had been a traffic study, relative to the Old County Road
residents, held on San Pablo Avenue between the hours of 8:00 AM and 3:30 PM.
We responded, at the meeting, that the study should have been between the hours
of 6:00 AM and 6:00 PM. Since you did not conduct the study during the time we
requested, you missed the commute traffic of both construction workers and plant
workers of TOSCO.

4. The traffic congestion on 880 was also discussed. As the traffic slows in the
morning and evening, the people who travel east and west take off 880 at the
Rodeo and Crockett exits to avoid several miles of stop and go traffic. This problem
should be reviewed further since the west turn from San Pablo Avenue to Old
County Road is a killer.
5. There have been more fatalities than I would like to remember. We were told that
due to the extra cost of the retaining walls, the road could not be widened. We
stated at the meeting that the bike lane could be easily utilized along the railroad
tracks and the waterfront clear into Martinez (This was not mentioned in the
meeting summary). If the lanes are reduced from four to two and the truck travel is
increased, the accidents will continue to increase.
The Tormey residents have requested that the Cummings Skyway be aligned on the
west side of Tormey with San Pablo Avenue. The alignment would eliminate the
following:
• The dirt fill east of us which will eliminate the air quality problem;
• The hazardous left hand turn into Tormey;
• The problem with the deer and red fox that now travel through_ the ravine freely;
• The problem with having two sections for cattle grazing;
• The truck hazardous spills which occur; and
• The additional noise problem from the trucks traveling by our community 24
hours a day.
Your current plan simply removes the transportation of hazardous materials from the
community of Rodeo and places it in the community to Tormey.
We have been requesting this since the first transportation meeting which was over a
year ago. It appears that our request has fallen on deaf ears. We cannot support the
Cummings Skyway extension project as written; further studies, which also include the
community, are needed.
Attached for your information and review is a copy of.a news article from a reporter of
the Crockett Signal. This reporter was the only reporter at the June 23, 1997 meeting.

Dear Ms. Bueren:
This letter is to voice our vehement opposition to your current plans to extend Cummings Skyway
and reduce the lanes on San Pablo Avenue. These plans have been drafted with complete
disregard to their effect on the residents of Tormey. Your proposals resolve the problem of traffic
through Rodeo and Crockett, only to create traffic and safety problems at the expense of Tormey.
Why isn't it possible to create a long-term solution? Supervisors need to take all their
constituents into account. Your proposal is a myopic short term solution that does nothing but
squander public resources while shifting problems from some to others. Why is not possible to
connect Cummings Skyway west of Tormey and alleviating the safety and saving the county from
having to deal with future problems which will arise from Tormey residents? I'm sure the
additional cost would be worth creating a true solution instead of a quick fix. Our public
representatives now seem to be too concerned with solutions that do not take the future into
account. You need to consider the long-term safety of the citizens, the quality of life of Tormey
residents. Representative government should take constituents into account even if they cannot
afford the same type of legal representation as Tosco might.
We support the letter written to you on July 3rd, by Richard Zampa on behalf of all Tormey
citizens. His views represent the views of our community. We expect the issues raised to be
addressed.
Sincerely,
Sherry& Harold Hutson

RE: Cummings Skyway Extension Project
Dear Mr. Kirkpatrick:
Thank you for your comments on the Negative Declaration for the Cummings Skyway Extension Project.
The following is our response to your comments.
IMPACT TO DISTRICT FACILITIES
We recognize the importance of the EBMUD's Selby Reservoir and are designing our road project to
avoid any impacts to your facilities. Our proposed alignment is east of the access road to your reservoir.
However, we will need to acquire some right.of way from EBMUD as the road goes through your
property. Once we have environmental clearance for the ;project;-our Real Property and Design
Divisions will be in contact with you regarding right of way,issues. We have looked at two alignments
for the project, one west of your reservoir and the preferred alignment which is east of your reservoir.
We expect that our preferred alignment will be compatible.with,your operations and maintenance of your
reservoir.
WATER SERVICE
We will incorporate water conservation measures into the design and the construction of the project.
We will be seeding the cut and fill slopes for the road with native grasses. No irrigation will be provided.
I hope this addresses your concerns. The Negative Declaration is scheduled before the Board of
Supervisors on August 12, 1997. Please call me at (510) 313-2342 if you have any questions.

RE: Cummings Skyway Extension Project
Dear Mr. Wiese:
Thank you for your comments on the Negative Declaration for the proposed Cummings
Skyway Extension Project.
We are in agreement with your comments under.Recreation regarding the recreational
benefits the proposed Cummings Skyway Extension will-have. The County is proposing
to provide bike lanes on San Pablo Avenue which will be the Bay Trail segment between
Rodeo and Crockett. Cummings Skyway Extension will have.shoulders to accommodate
bicycles and pedestrians providing an .important link between the Bay Trail and newly
acquired Park District land.
In your comment on Section 13f, Traffic hazards to motor vehicles, bicyclists and
pedestrians, you refer to the need for widening the existing Cummings Skyway over
crossing of 1-80 to provide for bike, lanes to connect the proposed bike lanes on the
extension with those on the existing Cummings Skyway. We agree with you -omments
and have made a similar comment to Caltrans on the Carquinez Bridge Draft
Environmental Impact Statement.
In your comment on Section 8, Land Use, you refer to the County's condition of approval
for the Pointe Crockett subdivision providing for right of way for a Class I multi-use trail
parallel to the Cummings skyway Extension. The County's conditions of approval for
Pointe Crockett do require the dedication of right of way for trails. The Conditions of
approval state that the dedication will be consistent with a February 25, 1993 letter from
Wickland Oil to Bob Doyle of the East Bay Regional Park District at the time the final
subdivision map is filed. Wickland has indicated to county staff that they are willing to
dedicate the right of way for the Cummings Skyway Extension prior to filing their final map
for Pointe Crockett to expedite the construction of the road project. We have not had
discussions with Wickland Oil regarding the timing of the trail dedication. However, the
design of the Cummings Skyway Extension will not interfere with the proposed future trail.
hope this has addressed your comments and concerns. The Negative Declaration is
scheduled before the Board of Supervisors on August 12, 1997. Please call me at (510)
313-2342 if you have any questions.

Crockett, CA 94525 RE:Cummings Skyway Extension
and San Pablo Avenue Projects
Dear Mr. Zampa:
.. .... .. ...
This is in response to your letteri dated July 3, 1997,-re.garding the Cummings Skyway
Extension and the San Pablo Avenue projects which were discussed at the public meeting
held in Rodeo on June 23;-A907.
1. In your first pointsyou bring up the discrepancy in the acciident data reported,
citing that there have been four deaths due to accidents;1:not two as stated in the
public meeting summary. You are correct in that there were four deaths. An
accident is reported as a property damage only, an-injury-or-as_a.fatality. The two
fatal accidents recorded on San Pablo Avenue refer to the.number of accidents that
resulted in.a fatality, not the number of people that were'kill,ed.
2. Trucks to and from:-Wickland Oil primarily use-thel 8b ramps in Crockett, so
there, is not an.expected increase in truck traffic by Tormey..from .Wickland's
operations once the'Cummings Skyway Extension. is constructed. Tosco has
reported they anticipate averaging 50 to 80 truck trips ih each direction on San
Pablo A nIpe by Tormey when they begin using_Gummings'Skyway. The majority
of the trips"will be to the their carbon plant on Highway 4. There would be sufficient
capacity; on San Pablo Avenue for these additional truck trips even with the
proposed restriping project. The restriping projectincludes truck climbing lanes to
minimize.the impact of slow moving vehicles on.other traffic:.
3. The traffic study'included a twenty four hour count of vehicles on San Pablo
Avenue just east of Old County Road. The count was taken midweek while school
was in session. The total volume was 3,900 vehicles per day. The morning peak
occurred around 6 a.m. with about 350 cars in the westbound direction and 125 in
the eastbound direction. The afternoon peak occurred at about 3:00 p.m. with
approximately 400 cars per hour eastbound and 125 westbound. Therefore, total
existing traffic was considered in developing both the Cummings Skyway Extension
Project and the proposal to restripe San Pablo Avenue.
4. Existing and projected traffic on 1-80 was also considered in the proposal to
restripe San Pablo Avenue. The studies show that the future volumes on San.
Pablo Avenue are not expected to increase. The proposed reconfiguration would "
easily handle the existing and future traffic volumes. The restriping of San Pablo
Avenue would provide for left turn lanes at intersections which is a safety
enhancement. This would allow vehicles a safe place to wait, out of a through
traffic lane, to make a left turn.
R. Zampa
July 31, 1997
Page 2
5. The County is interested in the safety of the traveling public. The proposed
restriping of San Pablo Avenue would have safety benefits incorporated into the
project such as left turn lanes at intersections, the provision for passing on the
uphill stretches to minimize the inconvenience of traveling behind a slow truck or
the likelihood of unsafe passing, and right shoulders for recovery for errant
vehicles, safe refuge for disabled vehicles and for bicycles and pedestrians to share
the roadway. We are also considering centerline treatments, such as raised bumps
for striping and delineators that would clearly mark the centerline and let drivers
know if they were crossing it.
San Pablo Avenue is shown as a bike route in the Countywide Bicycle Action Plan
and the 1989 Bay Trails Plan shows San Pablo Avenue as the Bay Trail segment
between Rodeo and Crockett. This is primarily because.of the public safety issues .
associated with putting a trail facility through a refinery and in an active rail corridor.
The East Bay Regional Park District is interested in eventually providing a separate
bicycle and pedestrian facility between Rodeo and Crockett, however the timing of
such a project is uncertain. Even with an off road bicycle and pedestrian facility,
it would still be preferable to have shoulders on San Pablo Avenue for safety
reasons as well as for bicycle access.
Regarding your comment to align the Cummings Skyway Extension on the west side of
Tormey, the County's preferred alignment is the one east of Tormey because it is less
steep than a western alignment and because of right of way issues with the Wickland Oil
tank. However, we did hear your concerns at the early meetings we held on the project
and our environmental consultant specifically looked at the noise and air quality issues
that you had raised. Our consultant analyzed the eastern alignment as to whether it would
create additional air quality impacts due to the earth fill for the roadway and found it not
to be the case.
As to the noise, the studies show that the project does not cause significant noise impacts
to Tormey. At the meeting in Rodeo, I stated that we would monitor after project conditions
to see if there is an increase in noise levels and, if it is found there is, we would provide
for mitigation.
The left hand turn into Tormey can be made safer with the provision of a left turn pocket
on San Pablo Avenue.
The environmental studies did not indicate an impact to the native wildlife in the area.
Regarding the impact to grazing cattle, it is our understanding that Wickland leases their
property on a yearly basis for cattle grazing. In conversations with Wickland Oil, they have
indicated that a cattle crossing is not necessary and not worth the additional expense to
the project. However, the lessee is interested in having one provided and we are currently
looking into the cost and feasibility of providing a cattle crossing under the Cummings
R. Zampa
July 31, 1997
Page 3
Skyway Extension. Another possibility that would at least partially address the lessee's
concerns is to provide water for the cattle on both sides of Cummings Skyway and we are
also investigating this option.
In regard to your concern about the increase in trucks and exposure to hazardous
materials, there will be an increase in truck traffic on San Pablo Avenue by Tormey, which
does increase the possibility of spills in the area. However, the increase in trucks is due
mostly to redirected trucks from Tosco that currently go through Rodeo to access 1-80.
The majority of Tosco's trucks will be carrying raw petroleum coke to their facility on
Highway 4 and returning empty. The coke is not considered a hazardous material and the
trucks will generally be covered to minimize spillage and dust. Vendors deliver a variety
of hazardous materials to the refinery in varying quantities. Tosco currently receives bulk
deliveries of anhydrous ammonia, which is an acutely hazardous material. The bulk
deliveries of anhydrous ammonia are being phased out and will be eliminated by
December 31, 2001. Bulk deliveries of chlorine have already been phased out at the Tosco
refinery.
I hope this addresses the concerns raised in your letter. The environmental document for
the Cummings Skyway Extension project is scheduled before the Board of Supervisors on
August 12, 1997. The San Pablo Avenue project is not yet scheduled for the Planning
Commission or the Board of Supervisors. I intend to have additional meetings with
representatives of the communities of Rodeo, Crockett and Tormey before proceeding
further on this project and will keep you informed as to when they are scheduled.
I have enclosed a copy of the environmental studies for your information. Please call me
at (510) 313-2342 if you have any questions or need further information.

Crockett, CA 94525, RE:Cummings Skyway Extension
and San Pablo Avenue Projects
Dear Mr. and Ms. Hutson: .
This is in response to your;letter, dated July 19, 1997, regarding the Cummings Skyway
Extension and the San Pablo"Avenue projects.
Regarding your comment to align the Cummings Skyway Extension on the west side of
Tormey, the County's preferred alignment is the one east of Tormey because it is less
steep than a.westem alignment and because of right of way issues with the Wickland Oil
tanks. The steepness of the Cummings Skyway Extension is important because the road
will be used by trucks. At the early public meetings on this project, a citizen from Tormey
did express concern about the.eastern alignment.and the potential impacts to air quality
and noise in:Tormey. Our environmental consultant.specifically looked at the noise and
air quality issuesthat were raised. Our consultant analyzed the.eastern alignment as to
whether it would_ create additional air quality impacts due to the earth=fill.for the roadway
and found it not to be the case. As to the noise, thestudiesshow that the',project does not
cause significant noise impacts to Tormey. At a meeting in Rodeo, I stated that we would
monitor after project conditions,to see if there is an increase in noise levels and, if it is
found there is, we would provide for mitigation.
The County is interested in the safety of the traveling public. The proposed restriping of
San Pablo Avenue would have safety benefits incorporated into the project such as left
turn lanes at intersections, the provision for passing,on the uphill stretches to minimize the
inconvenience of traveling behind a slow truck or the likelihood of unsafe passing, and
right shoulders for recovery for errant vehicles, safe refuge for disabled vehicles and for
bicycles and pedestrians to share the roadway. We are. also considering centerline
treatments, such as raised bumps for striping and delineators that would clearly mark the
centerline and let drivers know if they were crossing it.
San Pablo Avenue is shown as a bike route in the Countywide Bicycle Action Plan and the
1989 Bay Trails Plan shows San Pablo Avenue as the Bay Trail segment between Rodeo
and Crockett. This is primarily because of the public safety issues associated with putting..
a trail facility through a refinery and in an active rail corridor. The East Bay Regional Park
District is interested in eventually providing a separate bicycle and pedestrian facility
between Rodeo and Crockett, however the timing of such a project is uncertain. Even
with an off road bicycle and pedestrian facility, it would still be preferable to have
shoulders on San Pablo Avenue for safety reasons as well as for bicycle access.

hope this addresses the concerns raised in your letter. I have enclosed a copy of our
response letter to Richard Zampa for your information. The environmental document for
the Cummings Skyway Extension project is scheduled before the board of Supervisors on
August 12, 1997. The San Pablo Avenue project is not yet scheduled for the Planning
Commission or the Board of Supervisors. I intend to have additional meetings with
representatives of the communities of Rodeo, Crockett and Tormey before proceeding
further on this project and will keep you informed as to when they are scheduled.
I have enclosed a copy of the environmental studies for your information. Please call me
at (510) 313-2342 if you have any questions or need further information.
Very truly yours,
